I bought the game from Wildtangent/wildgames yesterday and I've noticed a weird issue which I dont know if is a bug or some "feature" of the game like tiredness or something.

When driving the rig it can suddenly violently turn left or right usually ending up crashing into another car/barrier or jackknifing the rig. This has happened with and without cruise control, locations are random.

At first I thought it might be some "falling asleep at the wheel" thing but was not aware this is a feature in the game. Also thought it might be a tire blow out. Is there such features or is this a bug?

This happens without using the brakes, most of the time I'm just going in a straight line, sometimes round a bend.

Aside from the mouse & keyboard, what other control devices do you have connected? This, and a few other games have a problem when running several control devices at the same time. IE: Steering wheel, joystick, 360 pad, and others.

This game is very difficult to run soley on a keyboard/mouse. If you don't have a steering wheel device, I simply would not invest in it. There are so many things going on that a keyboard/mouse is just not practical.

Are you running with ACC (cruise control) on?
This gizmo has a tendency to slam the brakes when adjusting speed to vehicle in front. So going above 65 mph with any truck will often make you crash. above 70 and it's all going to hell fast.

Otherwise, adjust your sensitivity. both steer and center sliders. a must for keyboard. I have very little problems actually.
